Transcription suppressor Musculin (MSC) is enriched in pro-inflammatory Th17 and IL-22-producing ILC3s. While MSC mice survived DSS-induced colitis, MSC mice showed elevated pro-inflammatory cytokines with severer pathology, reduced body weight, and earlier death. Reversal of colitis symptoms in MSC mice by IL-22 antagonism suggests the existence of MSC:IL-22 regulatory axis.
转录抑制因子肌细胞生成素(MSC)在促炎 Th17 和产生 IL-22 的 ILC3 中富集。虽然 MSC 小鼠在 DSS 诱导的结肠炎中存活下来,但 MSC 小鼠表现出更高的促炎细胞因子,更严重的病理,体重减轻,更早死亡。IL-22 拮抗作用逆转 MSC 小鼠的结肠炎症状表明存在 MSC:IL-22 调节轴。
